X-Basilosaurus
X-Basilosaurus Overview
Survivors looking at X-Basilosaurus in ARK: Survival Ascended will find an aquatic carnivore that is well-suited for deep-sea exploration, cave diving, and ocean resource runs. Tamed via passive taming (Exceptional Kibble is the optimal food), this carnivore enters service with 700 base Weight, providing massive inventory space. Reproduction is by live birth following gestation; juveniles mature over an extremely long period, one of the longest in the game. Once tamed it harvests Hide, Raw Prime Meat, Oil more efficiently than most player tools. Players who invest in one tend to keep it long after the early game has been left behind.

You can gather Hide, Raw Prime Meat, Oil from a X-Basilosaurus corpse. The corpse has 2,200 harvest health, allowing multiple hits before it's fully depleted.
Different tools yield different quantities - check the table below to pick the right tool for the resource you need. Generally, a Pick favors meat while a Hatchet favors hide and secondary materials.
| Resource |  Pick |  Hatchet |
|---|---|---|
| 40%~90~69 hits | 60%~135~55 hits | |
| 6%~7~69 hits | 6%~7~55 hits | |
| 40%~90~69 hits | 40%~90~55 hits | |

Estimates based on game-extracted data (weights, quantities, harvest multipliers, damage type chains). Each harvest event independently rolls each resource - higher weight = higher drop chance. Actual yields vary with RNG.
